Inert Gas Purge
A 0.125 in. / 3 mm port on the rear of the Temperature Controller is provided to allow you to blanket the
surface of the liquid in the bath reservoir with nitrogen or another inert gas to help prevent condensation
and dilution of the bath fluid.
Tap Water Cooling
Tap water cooling allows for more rapid bath cool down from high temperatures and/or more precise
operation at temperatures near ambient.
Heat only Circulating Baths feature an integrated cooling coil as standard equipment. The tap water
connections are made on the rear of the unit. Two 0.25 inch / 6.4 mm female NPT fittings are provided for
these connections.
Polycarbonate Viscosity Baths feature a cooling coil with two 0.375 inch / 9.5 mm OD straight barb
fittings at which the fluid inlet and outlet connections can be made. Either connection may serve as the
fluid inlet or outlet. Be sure to secure the tubing with the appropriate size hose clamps.
An optional cooling coil is available for use on Stainless Steel Open Bath systems. This cooling coil has
two 0.375 inch / 9.5 mm OD straight barb fittings at which the fluid inlet and outlet connections can be
made. Either connection may serve as the fluid inlet or outlet. Be sure to secure the tubing with the
appropriate size hose clamps.
WARNING: The fluid outlet must be connected and flow to a suitable drain or vessel located at a
level below that of the inlet.
Reservoir Cover Storage
Refrigerating/Heating and Heat Only Circulating Baths feature the LidDock
®
system to eliminate mess
when adding fluid or samples to the reservoir. Specially positioned notches in the inner lip of the top deck
allow you to stand the reservoir cover up upright over the bath opening, allowing condensate to flow back
into the bath.
